Coinbase announced on September 10, 2025, that non-fungible token (NFT) marketplace Opensea is among the new partners joining the second wave of Coinbase One’s onchain benefits program. Opensea confirmed the partnership on X, saying Coinbase One members will receive a 5% boost when they “power up” a Treasure Chest to earn shares in Opensea’s new prize vault and receive surprise “Shipments” beginning September 15. Coinbase One is Coinbase’s subscription service offering perks like free Base gas, airdrops and discounts for a monthly fee. Members must verify an onchain wallet to claim the Opensea benefits, and Coinbase noted membership terms, regional limits and auto-renewal apply.
